Manny Pacquiao defeats Jesse Vargas to reclaim World Boxing Organization welterweight title

Filipino southpaw Manny Pacquiao made a resounding comeback to professional boxing by reclaiming the World Boxing Organization welterweight title for the third time.

The 37 year-old Pacquiao won the title contest against former champion Jesse Vargas with a unanimous decision victory in his comeback fight today.

The 37-year-old Pacquiao systematically dismantled the former welterweight champion despite Vargas' size and reach advantage.

He used a short right-handed counterpunch to floor Vargas in the second round en route to a one-sided win in front of a crowd of 16,132 at the Thomas & Mack Center.

"I feel happy," Pacquiao said. "I'm trying every round to knock him down but also not be careless." Pacquiao, 59-6 with two drawn and 38 knockouts, showed he still has a lot left in the tank but he failed to get the knockout victory that has eluded him for the past seven years.

All three judges scored the bout for Pacquiao, two of them by 118-109 and the other by 114-113.

Pacquiao won the WBO title for the first time in 2010 when he beat Miguel Cotto. He lost it two years later to Timothy Bradley, then got it back by winning the rematch with Bradley in 2014.

He then lost it last year to the now-retired Floyd Mayweather, who had a front row seat for Saturday's bout. "Yes I invited him to come tonight," Pacquiao said of Mayweather.

Asked if he wanted a rematch with Mayweather, Pacquiao said, "We will see."

Pacquiao said he was retiring following his April 9 two-knockdown victory over Bradley in their third fight. Pacquiao looked impressive in stopping Bradley, showing that he has recovered from a shoulder injury which hampered him in his mega fight against Mayweather in May 2015.
